Local Government as Primary Access Point: “We recommend that local governments be the primary access point for local land information” (p. 4, 77).


Local Government Data Requirements: “We recommend that local governments maintain land data compatible with a multipurpose cadastre and transmit these data to higher levels of government when needed” (p. 77).

IV.
TECHNICAL ISSUES

Technical Studies: “We recommend that technical studies continue to be sponsored by the federal government to identify consistent land information and display standards for use among and within federal agencies and between federal and state governments. These studies should rely on the authority of state governments to adopt the standards and organize the data collection, in cooperation with the federal government to ensure compatibility on a national basis, delegating these functions to local governments where appropriate” (p. 3).

Details

The report stated that the following technical subjects should be addressed (p. 105):

  1. Integrating mechanisms for cadastral, cartographic, engineering, and geodetic surveying for federal and federally supported programs;

  2. Integrating mechanisms for storage and retrieval of other land information in data files; [and]

  3. Procedures for development of local systems, leading to the distribution of prescribed methods and rules for ties to geodetic coordinate systems and adjustment of state plane coordinates for property boundary surveys….

  • Map Compatibility: The report also recommended that the technical subject of “compatibility among the large-scale maps to be produced by the individual counties within each state” should be addressed (p. 87).

  • Standard Manuals: “We recommend that standard practice manuals describing specific survey methods and rules of adjustment for reliable determination of coordinates for property boundary corners be made available to the local land surveyor and enforced at each government level” (pp. 49-50).

  • Vertical Datums: “We recommend that local vertical datums be referenced to the latest National Geodetic Vertical Datum” (p. 51).

  • Tidal Benchmarks: “We recommend that tidal benchmarks be established along the east, west, and Gulf coasts at adequate intervals to permit local land surveyors to define riparian boundaries correctly and accurately” (p. 51).

  • Base Maps: “We recommend that base maps be grid oriented, tied to the national geodetic control system, and updated regularly” (p. 53).

  • Cadastral File: “We recommend that there be created a new cadastral file containing the records of boundary information referenced to the identifier number of each cadastral parcel” (p. 59).

  • Field Notes: “We recommend that the cadastral agency adopt minimum standards for field notes and mandatory filling thereof” (p. 72).
